Hi, I’m having some issues with the time it takes to render viewports. This started a few months ago, when I was working with a very large SKP file, so I initially thought the file size was the problem. However, I’m now working with a much smaller file, and the issue persists. Rendering in **Raster mode is extremely slow**. Every time I resize a viewport, it takes 30 seconds or more to render. A few months ago, this process was practically instantaneous. Today, while working on the smaller file, I accidentally switched the rendering mode to **Vector**. I expected it to be even slower, or perhaps to freeze SketchUp (become unresponsive or even crash with a BugSplat error). However, I was surprised by how quickly it rendered! The scene had very simple geometry, yet Raster mode was incredibly slow. I also tried **Hybrid mode** , but it was just as slow. Could the problem be related to texture loading? I’m not sure what’s causing this, but I’d really appreciate some help figuring out how to fix it. It’s becoming quite frustrating because I’m used to Raster mode being fast and Vector mode being slow, but now the situation is completely reversed. I have a video on this Google Drive file that exemplifies my problem: [https://drive.google.com/file/d/1cmGHv9oLSfsh9RKjUZ0SLEQr6tNpBRn0/view?usp=sharing](https://drive.google.com/file/d/1cmGHv9oLSfsh9RKjUZ0SLEQr6tNpBRn0/view?usp=sharing) ---

Share the actual LayOut file so we can see what you are working with. ---

There are many excessively large texture images in the model … ![Screenshot - 11_13_2026 , 8_28_52 AM](https://global.discourse-cdn.com/sketchup/original/4X/e/b/6/eb6c78b49a0552e096006129ccee0f676d30a45a.png) (a few of those large textures) … and a lot of viewports in your LayOut document. Even in Raster rendering those large textures will take longer to render, especially when you have LayOut rerendering every viewport. Two things you can do to mitigate this. First, reduce the size of the large textures to something reasonable. Second, turn off Auto Render and manually render viewports that need to be updated. When you get toward the end, turn on Auto Render and go away for a little bit to let LayOut update all of the viewports. You could do more to simplify the model which would help, too. By the way, be very careful with the viewports. You’ve overridden the Camera position for a number of them. This one for example as well as the one to its right and the one above it. ![Screenshot - 11_13_2026 , 8_44_40 AM](https://global.discourse-cdn.com/sketchup/original/4X/e/1/e/e1e634007a12b81fa19cc6830ba65e002bd11192.png) If something happens to reset the camera you will create a lot more work for yourself than if you had just made the appropriate scenes for those views in the SketchUp and used them without overriding the Camera. Here I’ve reset the Camera for that viewport. ![Screenshot - 11_13_2026 , 8_46_36 AM](https://global.discourse-cdn.com/sketchup/original/4X/6/6/1/661b8bcb6d0d01b0e1ae18582add538f8afcb4ca.png) Here’s rendering that viewport from Vector to Raster after having cleaned up the model a bit. ![raster](https://global.discourse-cdn.com/sketchup/original/4X/1/d/0/1d0591751e5e4f417271fe83239bc76d21b5ff56.gif) I would also suggest that you use tags to control object visibility in scenes instead of Hide. That can help to improve performance and it will allow you to work with fewer scenes in the SketchUp model making it easier to manage. Here I’ve turned on Hidden Objects. ![Screenshot - 11_13_2026 , 9_00_49 AM](https://global.discourse-cdn.com/sketchup/original/4X/f/d/d/fdd1c68ffa51e66f37cb492aa5898be06957bb8f.png)
